You aren't talking about a B.O.V. here I believe, you are talking about a waste-gate. Correct? Reason why I state this is because the two valves serve different functions in the system.

Waste gate is meant for regulation of induction system pressure. Blow off valve is meant for reduction of induction system pressure spikes when the throttle blade closes abruptly and the waste gate doesn't compensate quickly enough.

 

im talking about the bov.. all ? have been ans. i just need to know how much vac i have. but i got it today. and i know the diff between a WG and BOV

 

Check, just making sure. I might have not been following your description closely enough, I did not intend to cause any . Glad you got your vacuum reading figured out. Vacuum gauge do the trick?

 

yep..i forget that my boost gauge goes to vac...lol thanks

 

i have a 20# spring in mine since my vac is running at best of 19...it only releases pressure in the hi rpm's just after getting out of boost
cant see how anyone uses a 6 or 7# spring hence the BOV stays open most of the time

 

Mine does hang open a little at idle so I'm going to try the 9lb and 11lb springs with a different vacuum source. I have mine pulling vacuum off of the brake booster and it is really slow to respond which is why I went with the lower spring.

 

i run all my boost/vac lines from a block simular to this one that is mounted on the passenger side firewall...very nice and instant vac/boost pressures to all components:http://www.full-race.com/catalog/pro...oducts_id=1104

 

I just bought one like that a couple of days ago. Hopefully I will be installing it this weekend so I can play with the wastegate spring.

 

2ktransam let me know how that works for ya.

 

Will do. How long before you have your new setup together?
